hwmon: (tmp102) Use device_property_read_string API

Replace of_property_read_string() with the preferded
device_property_read_string() in the probe function to
read the device label property, improving the driver
compatibility since this method is not limited to
Device Tree only.

Also drop the now unnecessary __maybe_unused from tmp102_of_match.
